Bitcoin Maintains Market Dominance Amid Shifts Toward Altcoin Growth Phases

The current cryptocurrency cycle shows Bitcoin maintaining a dominant market share of around 58-59%, supported by institutional investments such as U.S. spot Bitcoin ETFs. Traditionally, altcoin seasons occur when alternative cryptocurrencies outperform Bitcoin, driven by capital rotation into high-growth projects like DeFi and AI tokens. While Bitcoin leads initial rallies, altcoin seasons bring increased volatility and trading activity. The evolving market structure reflects a balance between Bitcoin's liquidity appeal and investor interest in diverse digital assets.
